Coating Hardness and Modulus Measurements (Oliver-Pharr)

Mechanical characterization is critical in the process and manufacture of films, including the quality of coatings in the automotive industry, as well as during process control of front-end and back-end semiconductor manufacturing.

The iMicro nanoindenter is capable of measuring the hardness and modulus of coatings for a wide variety of materials, from ultra-soft gels to hard coatings. The high speed assessment of these properties enables quality control and assurance on production lines.

High Speed Material Property Maps

For many materials, including composites, the mechanical properties may vary widely from one area to the next. The iMicro provides a sample stage movement of 100mm in the X and Y axes, and 25mm in the Z axis, allowing testing of a wide range of sample heights over a large sample area. The optional NanoBlitz Topography and Tomography software can quickly generate color maps of any of the measured mechanical properties.

Yield Stress-Strain

During material elastic deformation, the strain increases in proportion to the applied stress, with the constant of proportionality being the Young’s Modulus of the coating material, E. The entire stress-strain curve of a material, including the yield point, can be determined using nanoindentation with a flat-ended cylindrical punch and patented 乱伦社区 analysis of the resulting force-displacement data.

ISO 14577 Hardness Testing

The iMicro nanoindenter includes a pre-written ISO 14577 Test Method that measures material hardness in compliance with the ISO 14577 standard. This test method automatically measures and reports Young’s modulus, instrumented hardness, Vickers hardness and the normalized work-of-indentation.

Polymer Tan Delta, Storage and Loss Modulus

The iMicro nanoindenter is capable of measuring both tan delta and the storage and loss modulus for ultra-soft materials, including viscoelastic polymers. Storage and loss modulus and tan delta are important properties of viscoelastic polymers, whose energy is stored as elastic energy and dissipated as heat. Both of these metrics measure energy dissipation in a given material.

Quantitative Scratch and Wear Testing

The iMicro can perform scratch and wear testing on a variety of materials. Coatings and films are subjected to many processes that test the strength of these films and their adhesion to the substrate, such as chemical-mechanical polishing (CMP) and wire bonding. It is important for these materials to resist plastic deformation during these processes, and to remain intact without blistering up from the substrate. Ideally, a dielectric material will have a high hardness and elastic modulus because these parameters help define how the material will react when subjected to manufacturing processes.

High Temperature Nanoindentation Testing

Nanoindentation at elevated temperatures is critical to characterizing material performance under thermal stress, especially for quantifying failure mechanisms during thermomechanical processing. Varying the sample temperature during mechanical testing enables not only measurement of thermal-induced behavioral changes, but also quantification of transition plasticity of materials that are not easily tested on the nano-scale.

Continuous Stiffness Measurement (CSM)

Continuous stiffness measurement is used to quantify dynamic material properties, such as strain rate and frequency-induced effects. The CSM technique involves oscillating the probe during indentation to measure properties as a function of depth, force, time, or frequency. The option comes with a constant strain rate experiment that measures hardness and modulus as a function of depth or load, which is the most common test method used across academia and industry. CSM is also used for other advanced measurement options, including the ProbeDMA? method for storage and loss modulus measurements and AccuFilm? substrate-independent measurements. The CSM is integrated into the InQuest controller and InView software to deliver ease of use and data quality.

The InForce 50 actuator is compatible with the CSM, NanoBlitz, ProbeDMA, biomaterials, sample heating, scratch, wear and ISO 14577 testing options. Tips are interchangeable among the entire line of InForce actuators.

300°C Sample Heating

The 300°C sample heating option allows the sample to be placed into a chamber for uniform heating while simultaneously undergoing tests with either the InForce 1000 or InForce 50 actuators. The option includes high-precision temperature control, inert gas backfill to reduce oxidation, and cooling to remove waste heat. ProbeDMA, AccuFilm, NanoBlitz and CSM are all compatible with the sample heating option.

Hard Coatings

Typically, < 5?m thick hard coatings are applied to materials for surface protection, increased wear resistance, friction/lubrication, temperature resistance, and biocompatibility. The iMicro system can accurately perform ISO standardized nanoindentation testing and measure elastic modulus and hardness of the coating without influence from the substrate. The iMicro nanoindenter is also capable of measuring scratch hardness and wear resistance. In the case of high surface roughness coatings, the NanoBlitz 3D option can be used to quickly and quantitatively assess material properties.

Semiconductor Wafers

Semiconductor manufacturers often strive to produce thin films with high mechanical integrity, but low film flexibility can lead to cracking or delamination. Undetected defects at the substrate and epitaxial layers can also result in latent defect and crack propagation, which can lead to device failure. 乱伦社区 nanoindenters are capable of measuring elastic modulus and hardness of the thinnest films, as well as fracture toughness and cracking threshold, all without artifacts from the underlying substrate. Correlating nanomechanical properties to process parameters is critical to maximize semiconductor device yield. Learn More
